Risk factors for non-impact ACL injury.

For non-impact ACL Injury10	Relevant to stroke	Relevant to case report
Genetics
Female Gender		Female Gender
Hormonal Concentration	Hormonal changes occur after stroke
Increased knee joint laxity	Laxity may be evident in patients with flaccidity especially during initial phase of motor recovery after stroke.
Decreased intercondylar notch width
Increased posterior tibial slope
Neurocognitive factors	Slow reaction time Processing speed Impulsivity Poor insight Impaired judgment Visuo-spatial impairment Neglect	Slow reaction time secondary to left MCA stroke.
Neuromuscular factors	Weakness Proprioceptive impairment Spasticity and Limb dystonia Associated reaction Co-contraction Ankle Clonus Imbalance Incoordination Fatigue	Weakness Imbalance Ankle Clonus
Prior ACL injury
Extrinsic factors	Ground surface, footwear	Uneven surface (garden) Wearing inappropriate shoes (open shoes)
